Sahih Muslim Book - 15, Hadith - 2954

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا أَبُو مُعَاوِيَةَ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ - رضى الله عنها - قَالَتْ كَانَ قُرَيْشٌ وَمَنْ دَانَ دِينَهَا يَقِفُونَ بِالْمُزْدَلِفَةِ وَكَانُوا يُسَمَّوْنَ الْحُمْسَ وَكَانَ سَائِرُ الْعَرَبِ يَقِفُونَ بِعَرَفَةَ فَلَمَّا جَاءَ الإِسْلاَمُ أَمَرَ اللَّهُ عَزَّ وَجَلَّ نَبِيَّهُ -صلى الله عليه وسلم- أَنْ يَأْتِىَ عَرَفَاتٍ فَيَقِفَ بِهَا ثُمَّ يُفِيضَ مِنْهَا فَذَلِكَ قَوْلُهُ عَزَّ وَجَلَّ (ثُمَّ أَفِيضُوا مِنْ حَيْثُ أَفَاضَ النَّاسُ)

It was narrated that Aisha said: “The Quraish and those who followed their way used to stand at Al-Muzdalifah, and they were called Al-Hums and the rest of the Arabs used to stand in Arafat. When Islam came, Allah commanded His Prophet (SAW) to go to Arafat and stand there, then depart from there. That is the verse in which Allah says: ‘Then depart from the place whence all the people depart.’”
